There's no allied equivalent to the Stuka Dive Bomb, especially considering cost and mode of operation.
Damage nerf to 280 means that T34/85's will take an equal number of shots to die as before the damage nerf. This change will only affect the survivability of stock medium allied T3 tanks.
Sure. Mark Target could do with a nerf, though.
Trash doctrines and abilities will have to be reworked. From my perspective (and all of us share this viewpoint) is that doctrines should not be "carried" by a single OP ability (see artillery cover).
Ideally, the doctrine should be composed of useful abilities that also make sense when bundled together. Thankfully, both Tactical Support and Elite Armour have useless abilities that can be buffed to make doctrines feel more thematic, rather than make singular units define the doctrine.
Damage nerf means that cost can go down, by a lot.
Comets already require 3 shots to go down to Elefant/JT, and they will still require 3 shots to go down post-change.
This is similar to demo-charges, which are 90MU all-or-nothing investments.
With Elefant/JT damage nerf we merely want to avoid those things from being too good at wiping things.
Stuka dive bomb only kills something if you are deaf or braindead - you can't use them in base anymore so there is no way to wipe a blob with it.
Damage nerf is simply stupid because the JT/elefant are suppose to counter the bullshit super-heavy with ridiculous amount of health - if you want to nerf damage, then nerf the IS2/ISU armor or health as well, or you have to decrease the reload time (it's 8 sec!! how can you not get away?)
Right now Paks/Raketens, even stuG, on top of taking 6-7 penetrated shots to kill a 1000+ health super heavy, will often bounce off too much at bad RNG, thats why you resort to the more reliable, yet extremely expensive JT/Elefant (ISU can counter infantry, these 2 heavy TD can't)
and you forgot that right now axis still need these units to push back the allies late game to win.
before Pz IV and Panther get buffed to an acceptable level of power on par with allies, so their mid game don't suck; you dont have anything to counter the extremely potent T34 spam - it's 80 fuel, come on; or in general allies medium spam until super heavy TD hits the field.
And even now you can swarm it easily with the amount of mediums you can get.
You need a good Pz4/Panther to compensate or axis will get massacre once allies get a critical mass of mediums.
Sturmtiger:
This was the only reliable blob counter for OKW against rifle/tommy blobs.
I can't say for now but MG34 still suck and there is nothing to reliably punish blobbers.
And of course, you talked about nerfing stuka so...
